三苄基氯化锡最初用格氏法制得。Keiti等曾报道由锡和苄基氯直接制备,这时溶剂对反应的影响很大:用水作溶剂时得到三苄基锡;用甲苯作溶剂时得到二苄基二氯化锡;用正丁醇作溶剂时三苄基氯化锡的产率只有61％。在反应体系中加入KI、KBr或H_3PO_4等催化剂,三苄基氯化锡的产率也只有60％。本文用DMF作溶剂,AlCl_3-I_2作催化剂,并首次在反应体系中加入镁、锌、铝和钠等使副产物氯化亚锡还原成活性很高的金属锡,后者再与等基氯反应,可使三苄基氯化锡的产率提高到91.3％。文中还报导三种尚
Tribenzyl tin chloride was first prepared using the Grignard method. Keiti et al. Reported that the direct preparation of tin and benzyl chloride, when the solvent on the reaction of a great influence: when using water as a solvent to give tribenzyl tin; with toluene as a solvent to give dibenzyl tin dichloride; with n The yield of tribenzyltin chloride was 61% when the alcohol was used as a solvent. In the reaction system by adding KI, KBr or H_3PO_4 and other catalysts, tribenzyl tin chloride yield of only 60%. In this paper, DMF as a solvent, AlCl_3-I_2 as a catalyst, and for the first time in the reaction system by adding magnesium, zinc, aluminum and sodium so that by-product stannous chloride is reduced to a highly active metal tin, Reaction, the yield of tribenzyl tin chloride can be increased to 91.3%. The article also reported three kinds yet
